Does anyone know how to solve these equations.

KCosA + YSinA = CSinB
KSinA - YCosA = CCosB

Hi

Take C to the Left side in both Equations

put sin Z = K/C & cos Z = Y/C ...z is an arbitrary constant

use relations sin x.cos y + cos x. sin y = sin ( x+y)
& cos x.cos y - sin x. sin y = cos (x+y)

simplify & you get

A-B = -z
A+B= -z ....

So B=0 & A= - z => A= -arctan(K/Y)



Plz verify the simplification

I've been solving the IK for the leg configuration of my hexapod robot, which i'm doin as my final year proj. It's almost completed, 'll be putting up a website soon.

Friends I need help for solving the following mathematical equations.

KCos(A) + LCos(B) = P
KSin(A) + LSin(B) = Q

Thanks & Regds
